Application filed January 25, 1.907. Serial No. 353,968.

. tion in shcet metal, und the object of the iinl'irovenient is to provide a. sheet inctel freine construction which nia-y be quickly and easily adapted to any variations in the walls et the top end sides of the opening.

Figure 1 is en elevation of the upper portion of u. freine. Fis. 2 is sectioned View of the lintel at line X inv Fig. 1. Fig. 3 is u sectional view of either side at line Y Y. Fig. 4 is e. slight modification of the cor struction shown in. Fig. 3. llig. 5 is s pien view of the under side of the lintel.

Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the brick, stone, or cein'ent wall of which reproof buildii'igs are usually constructed and 'upon which sheet nictnl frames are used. The jnnibs et each side of the opening to be framed are lpreferably first fitted with strips 11, and un inner strip 12'llmving the central lengthwise groove 13. Two side strips 14 are provided to -ft the molding of the sheet nietfel facing and hold it stiff. I

The sheet metal sides consist of the inold ings 15 and 16 for the jein-b end facings oll on the Wall. A lcnge' 17 is turned .inward the oute'il edges of themoldings 15 an 16. Cleats 18 are attached to the well 10 on each side by bolts 19, as shown, and `flanges 17V are held firml in piaci;4 nder cleats 18, as shown. olding 15 secured by suitable screyvsi`-y on thc jainbs'. Slotted openings 20 are prvlded in molding 15 over groove 13,

IMoldingl has the stop 21 for the door or Window formed `on'its inner edge, a channel piece 22 is' proyidedto hold stop 21 firmly in place' 'on the jamb and a second-channel piece 23 is provided for the screw bolts 24150 that the cannot compress the molded stop 21 out of A 'strip or bar 25 is rovided in groove 13'for bolts24 to screw lnto. Bolts 24 pass through suitable holes-in stop 21, and

t-put in place and channel pieces 22 find, 23, and through slotted opening 2() in pic-ce 15. It is nppercnt thut any inuccurecles of the thickness in. thc well 1() urre'easily adjusted by s slot 20 for catch bolt 24 down the face of the intcrlnp.

il slight modification in, the cci'istructicn oi the sheet motel molding v16 shown in Fig.

4, in which the sheet ine-tal stop 21 is mede in s sopa-rate piece from the remainder of the molding; the inner edge of the molding 16 extends through underneath channel i'iiece 22, and is held .firmly in place by se f 24, the edge 26 of the molded .stop L ing the inner edge of the molding forni shown in Fig. 3 is preferred on account of its greater strength in holding the door or Window 27.

In the .metal sheathing of -the lintel of the door freine it is necessary to 'rovidc for the settling together of the buil ing, end to so rovide that such unavoidable change may' e easily adjusted so that the freine will, not

bind the door or window Witliin it. The ii'ioldings 15 und 16 are attached at their outer edges by .flanges 17 and cleats 18. Esch ol the moldings, instead of extending :Across the under face of the lintel stop just outside of flic seine. Angle pieces 28 are provided et 'cs'ich side, being secured by suitiible screw bolts 29 through strips 14, and

.extending Within the opening beneath strip 11. Aslottcd opening 30 is provided between angle pieces 28 and strips 14 and moldings 15 and 16 to receive the inner ed es ofthe pieces 31 sind 32 which continue tie form of the door freine .with slot 2() in piece 3l to re ceive bolt 24 and stop 21 with the channel pieces .22 and 23 within the seme.- A strep 33 is rovided on the inner side of piece 31 to hold b screw bolts 35 are provided et each side between angle pieces 28 and pieces 31y and 32.

It is now apparent that the pieces 31. and

32 may be quic ly adjusted by screw bolts 35 and thusv accommodate the frame to the set' tling of the building Without4 buckling or bending the sheet metal cesing thereby spoiling its contour es Well as its metal finish.

t is a parent that the form of casing shown in $ig..3 might be continued across the lintel in the place of the form shown in Fig. 2 and serve a good purpose, but it would not accommodate theV settling of the building, and ccordin 1y the form shown in Fig 2 1s preferred lllie construction 'shown in ig. 2

er 25'in place. Coiled springs 34 and 95 .casing coinprnsed oli two `lengthw'ise imy l'screw bolts in seid perts and tie pi,

forms e springior resilient lintel which 'may beeeeily-adjnsted to the neturzil changes in the building and which may beuscd with any good forni of sh it metal casing und not part from this ent-ion.
